SPECIFICATION fori'nnglpart of Letters Patent No. '778,27 9, dated December 27, 1904. Application iled July 19, 1904i. i Serial No. 217,197.

a citizen of the United States, and a resident of Jersey City, in the county of Hudson and 'State of New Jersey, have invented certain new and useful Improvements in- Fireproof Shutters, of which the following is a specili-l cation.

This invention relates to reproof shutters, doors, ceilings, partitions, walls of buildings, and the like.

It comprises means whereby a circulation of air is obtained between the plates or surfaces of shutters, doors, and the like to make them reproof.

Referring to the drawings, Figure 1 represents the invention with an elevation of a pair of shutters and the accompanying casing. Fig. 2 shows a section of one of the shutters shown in Fig. 1 on the line as m. Fig. 3 represents a section of one of the shutters shown in Fig. l on the line Fig. 4 is a partial top view and section of Fig. l on the line m2 002. Fig. 5 represents a view similar to Fig. l modied and a partial section, as on the line m3 x3 of Fig. 7. Fig. 6 is a section of one of the shutters shown in Fig. 5 on the line mi mi. Fig. 7 is a partial top view and section of Fig. 5 on the line m5 m5.

Referring particularly to Figs. l to 4,' a shutter i-s shown consisting of a front plate A, from which extend longitudinal ducts B, that run into or are connected at their ends by the cross-ducts C. The longitudinal ducts B comprise the rear walls b, parallel to the front.y

plate A, the inclined side walls 6, and the connecting portions Z22, by means of which latter the said ducts are secured to the front plate A. The cross-ducts C comprise therear walls C', parallel to the front plate A, the end walls C2, perpendicular thereto, and the walls C3, parallel to the walls C2 and located between and near the ends of the longitudinal ducts B. In the front plates A and opposite the ducts C are formed openings a, each pair of whichare generally located adjacent to the ends of the ducts B. A latch E is journaled on the spindle E', from which latter extends on theoutside face of thel shutter the handle E2. A stop F is fastened to-one shutter, and

stop F is fastened to the other. One end, e, of the latch is bent at right angles to the body thereof to serve as a handle. The latch is shown as connecting the shutters, and by turning it in the direction of the arrow the shutters can be opened. The latch can be turned `by bearing up on the end e or by bearing down on thehandle E2. A suitable casing is shown at G, from which the shutters are swung, by means of the hinges g. It is evident that the combination of a plate with longitudinal and cross ducts and openings leading into the ducts secure means to circulate air through the ducts and against the plate, making' the plate and ducts tireproof.

It is evident that the invention can be applied to doors, ceilings, walls of buildings, partitions, and the like without departing from the spirit of the same. r

` In Figs. 5 to 7 there are'shown shutters with front plates A', longitudinal ducts B', extending from the rear faces thereof, and cross-ducts C". In the end walls C5 of the latter are formed the openings a, each pair of which are generally located to face the ends of the longitudinal ducts.

Having described my invention, I claim;

1. The combination of a plate, having a couple of rows of openings, ducts extending from the plate and covering each row of openings, other ducts connecting the ducts over thel said openings.

2. In a lireproof shutter the combination of a plate having openings at two opposite ends thereof, ducts extending from the plate over the lsaid openings, and other ducts connecting the ducts located over the said openings.

3. In a lireproof shutter the combination of a plate having a row of openings at the bottom portion thereof, and a row of openings at the top portion, a duct at the top portion of the plate over the row of openings therein, and a second duct at' the bottom portion of the plate and over the openings therein, and other ducts connecting the said ducts at the top and bottom portions of the plate.

4. In a pair of vireproof shutters the combination of a plate having openings for each shutter, ducts extending from the plate over the openings, other ducts connecting the ducts IOO over the openings, a latch journaled to one of the shutters a stop on one side of each shutter for the latch, a handle connected with the latch and extending on the outside of the Shutter, on the side of said shutter opposite to the side carrying the stops, a second handle extending from thelatch on the saine side of the shutter with the stops.

5. In a pair of ireproof shutters the combination of a plate for each shutter having openings for the circulation of air, vertical air-ducts extending from the rear face of the plate, cross-ducts connecting the Vertical ducts Vand over the openings in the plate, a latch journaled to one of the shutters, a stop on one side ot' each shutter for the latch, a handle 0n the opposite side of one of the shutters and connected with the latch, and other means on the latch to turn the latter on the side o't' the shutter opposite the handle.

Signed at Jersey City, in the count)7 of Hudson and State of New J ersey, this 12th day of July, A. D. 190e.
